VOCIA OUTPUT 4 WITH EXTENDED CAPABILITY (VO-4e)
The VO-4e is an enhanced networked audio output expansion device that allows the user to add four line-level and CobraNet® output
channels to be added to a Vocia system. The VO-4e can be congured for Channel-to-Channel or Device-to-Device failover and uses
comprehensive xed-chain digital-signal processing within the device, including volume control, ducking, equalization, compressor/limiter,
speaker crossover, delay, and output gain. Emergency Messages for life-safety systems are stored in non-volatile memory. Two RJ45
connectors on the rear of the device provide redundant connectivity to process control data, audio and power over an Ethernet cable.
In addition to this the VO-4e also has dual inputs for accepting power from an Auxiliary supply. The per-channel Paging relay provides a
contact closure when Paging is active on an associated channel.
FEATURES
• CobraNet audio output
• Channel-to-Channel and Device-to-Device failover
• Local non-volatile storage of Emergency Messages
• Dual PoE capable with alternate powering from auxiliary 24V DC supply (dual inputs)
• LED status and fault indication
- Chassis Fault, Activity and Status
- PoE Power
- Aux Power
- Output Channel Amp Fault, Activity and Signal Present
• Four Page Active Relays, Control Inputs and Control Outputs
• Speaker line monitoring and ambient noise compensation supported using ELD-1 and ANC-1 devices
• Software-congurable signal processing including volume control, lters, compressor/limiting, delay, speaker equalization, and output level
• CobraNet audio/control with dynamic use of available bundles over single Ethernet cable
• Dual CobraNet ports for redundancy
• Rotary switches for device identication
• IP30 Compliant
• CE marked, UL listed and RoHS compliant
• 19 inch, 1RU housing
• Covered by Biamp Systems’ 5-year warranty

VO-4e FRONT PANEL
Setup and Use
The Vocia software provides the interface for conguring and programming the VO-4e. The information supplied by this manual relates to
hardware installation, physical connections, device and channel failover concerns. For more details on software setup, please consult the
Vocia Software Help File.
Chassis Indicators Channel Indicators
System Indicators
The LED indicators on the front panel provide information and operational status of the unit and associated output channels. LEDs have
been grouped into Chassis and Channel indicators.
Chassis Indicators
These indicators relate to the entire unit (chassis).
PoE is a green LED indicator that will illuminate when PoE power is applied to the unit via either or both CobraNet ports.
Aux is a green LED indicator that will illuminate when an auxiliary DC supply is applied to the unit via either or both 24V Auxiliary power inputs.
Refer to the caution in the Rear Panel Auxiliary Power section.
Chassis Fault is a yellow LED indicator that illuminates when a Chassis Fault has occurred. There are two types of Chassis Faults that
can be reported depending on the severity of the problem. Flashing yellow indicates a Warning that means some aspect of the unit is not
performing within normal specication. Audio may still be passing but if the condition causing the warning is not corrected chassis failure
may occur. Solid yellow indicates a fault which means that some aspect of the unit has failed and audio may no longer be passing through
the device. Use Vocia software to determine the specic type of chassis warning or Fault that has occurred.
Activity is a two-color LED that indicates the conguration status of the device. A solid green LED indicates that the unit is congured.
A ashing yellow LED indicates the unit is active but uncongured. A solid yellow LED indicates the unit is congured and in standby.
Standby only occurs when a unit has been designated as a redundant device when Device Failover is enabled.
Status is a tri-color LED that indicates the health of the hardware. A green LED indicates that the unit powered up normally. A ashing
yellow LED is shown briey during the power-up self-test and will turn solid green upon successful start. A red LED indicates that the unit
experienced a problem during the power-up self-test.
Channel Indicators
These indicators relate to each of the four channels.
Amp Fault is a yellow LED that illuminates when the corresponding Amp Fault Input on the rear of the unit has been asserted.
Activity is a two-color LED that illuminates green when that channel is congured and actively passing audio and yellow when that channel is
congured and in standby. Standby only occurs when a channel has been designated as redundant channel in a failover conguration.
Signal is a tri-color LED that that indicates audio signal presence on the amplier channel. Green indicates that the audio signal level is between
-48 dBFS and -18 dBFS, yellow indicates a signal level between -18 dBFS and -2 dBFS, and red indicates clipping (above -2dBFS).
